GIS Data :: Web Maps

As an agency often involved with spatial information, the CGS is moving more and more to dynamic GIS data presentation for ease-of-use and for the many options that GIS tools allow. Almost all of our current projects and publications have substantial GIS components. We are in the process of implementing GeMS standards for our GIS metadata which will increase the utility of our entire GIS repository. We will be adding to this data Portal on a consistent basis as we produce new publications, and in many cases, update older data.

Many of our publications include GIS_Data directories as part of the downloadable package. As always, this data is free.

We will be building out our library of web applications that offer refined ‘views’ of Colorado geology and the associated derivatives of use to our various constituencies. At the moment, we are assessing our entire GIS dataspace for new packages that we can bring online in the next months.

GENERAL GEOLOGY

ON-001 — Colorado Earthquake and Fault Map — shows a variety of information including Cenozoic faults. (supersedes publications B-46 & B-52 & B-52B & IS-60)

ON-04.01 — StateMap Progression Map — shows the quadrangles that have been geologically mapped across the state, both USGS and CGS maps. Of Colorado’s approximately 1,800 7.5-minute quads, more than 500 have been mapped and there are usually around ten that are in progress at any one time.

ESRI, a major player in the GIS world introduced the online platform called StoryMaps in 2016. It has since become an important tool in conveying GIS information in a form that is more accessible to the general public. The CGS began working on a select number of projects with an eye on presenting them as StoryMaps:
